A collection of 19th century town maps of Mallow, Passage West, Queenstown (Cobh) and Youghal, County Cork. These maps are at a scale of ten feet to one mile, showing great detail in these towns.

This unique collection offers a rare insight into the life of an estate in east Cork during the mid-nineteenth century. The Standish Barry Estate Maps were donated to Cork County Library in 2001 by the family of the late Professor Dr Richard G. Barry.

The Ponsonby family were members of the landed gentry. This branch of the Ponsonby family was descended from John Ponsonby (1713-1787) speaker of the House of Commons in the Irish Parliament and second son of Brabazon Ponsonby, 2nd Viscount Duncannon and 1st Earl of Bessborough.
